Magnetic resonance imaging (MRI) brain: features
- Multiple bilateral high signal changes
- Multiple cortical-subcortical infarcts
- Mass lesions
- Confluent white matter changes
- Intracerebral haemorrhage (ICH)
- Subarachnoid haemorrhage (SAH)
- Cortical microhaemorrhages: with small vessel PACNS
- Radial linear contrast enhancement: case report
- Leptomeningeal enhancement
- The abnormalities may be uni-hemispheric
- The thalamus may be prominently involved
Cerebrospinal fluid (CSF) analysis
Cerebral angiography
Brain biopsy
